A bottle of wine is a container, typically made of glass, that holds fermented grape juice. It usually comes in standard sizes, with the most common being 750 milliliters. Wine bottles are often sealed with a cork or a screw cap to preserve the quality of the wine inside. Wine can be classified into various types, such as red wine, white wine, and rosé wine, each offering distinct flavors and aromas. The choice of grape variety, region, and production methods all influence the characteristics of the wine. Wine is often enjoyed during meals or special occasions.
